摘　　要：目的通过超声心动图诊断6例成人孤立性心肌致密化不全(INVM),探讨早期诊断该病的重要性。方法超声心动图多切面扫查,采用HP5500彩色超声仪,探头频率2～4MHz,重点观察近心尖1/3的心室心肌及心内膜。结果6例患者UCG特点,均为受累的心室腔内可探及大量突出的肌小梁和深陷的小梁间隐窝。病变心肌包括两层结构其一为心外膜侧的薄而致密的心外膜层,其二为心内膜侧厚而致密化不全的心内膜层。病变部位明显增厚并呈节段性运动减弱。结论UCG无创且特异性强,目前仍是诊断该病的首选方法。INVM应被单独归为一类特殊的心肌病。Objective: To apply echocardiography in diagnosis of isolated noncompaction of ventricular myocar^dium (INVM) in adults.Methods: Six patients with INVM underwent echocardiographic examination using HP5500 ultrasound system with the frequency of 2~4 MHz,and the observation was focused on ventricular^myo- cardium and endocardium at one-third of the apex.Results: All 6 patients showed typical echocardiographic ~images characterized by an altered structure of the ventricular myocardium with extremely thickened,hypokinetic segments consisting of two layers:a thin,compacted epicardium and an extremely thickened endocardium,resulting in an extremely thickened ventricular wall.Conclusion: Echocardiography should be the first choice to be applied in diagnosis of INVM,which is a distinct entity of specific cardiomyopathy in adults.
